Shademix
Shademix is a versatile color management platform that operates entirely within the browser, offering designers a unified workspace for sampling, converting, and harmonizing colors across multiple industry-standard systems including Pantone, RAL, NCS, and Munsell. It provides an eyedropper tool for images, live camera feeds, or screen picking, and supports dominant color extraction and palette building directly from visuals. The tool includes advanced color analysis features such as WCAG contrast ratio checking for accessibility compliance, color blindness simulations using Brettel transforms, metamerism previews under different illuminants, and CMYK gamut warnings to anticipate out-of-gamut clipping. A perceptually uniform OKLCH gradient generator allows for smooth transitions that maintain visual consistency. Shademix also offers robust palette management, enabling users to save, compare, and export palettes in multiple formats including JSON, CSS, PDF, and (with a Pro license) ASE, ACO, GPL, and design-tool-specific files for Figma, Sketch, Photoshop, and more. A print-ready check module provides resolution verification, bleed guides, and PDF output with crop marks for pre-press preparation. The application functions as a progressive web app (PWA), allowing installation for offline use, with all data stored locally in the browser. A free tier covers core functionality, while a Pro tier unlocks advanced export formats and additional capabilities.
